UNITED STATES ROBERT C. RUSSELL, OF PITTSBURGH, PENNSYLVANIA.

CARD INDEX.

Application led October 2, 1923. Serial No. 666,101.

To all whom it may concern:

Be it known that I, ROBERT C. RUssnLL, a citizen of the United States,and resident of Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in CardIndexes; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains, to make and use the same.

This invention relates to improvements in card indexes o-f the visibletype and more particularly to means, such as a shield, to protect thefree edge portion of the cards against injury or soiling,-an object ofmy present invention being to provide simple and efficient means forattaching the shield to the card without riveting, cementing orotherwise permanently securing the shield or protectonto the card, andat the same time insure attachment of the shield to the card so that itsaccidental displacement will be prevented.

With this and other objects in view, the invention consists incertainnovel features as hereinafter set forth and pointed out in the claims.

In the accompanying drawings;

Figure l is a front view of an index card showing the application of myimprovements thereto;

Figure 2 is a rear view;

Figure 3 is a horizontal sectional View on the line 3 3 of Figure 1, and

Figure 4 is a vertical sectional view on the line 4-4 of Figure 1.

In the drawing, an index card is shown at 1, and at its respective ends,near its lower edge, it is provided with notches or recesses 2, eachhaving an inclined edge 3 and an upper horizontal edge 4.

A shield or protector 5 preferably of transparent material, such asCelluloid, is applied to the front face of the card near its lower freeedge portion, and the lower edge of said shield is made with a smallange 6 which projects under the free edge of the card in a manner toprotect said free edge and also assist inpreventing upward displacementof the shield.

At its respective ends2 the shield is provided with integral, resilient`tongues or projections 7 which may be triangular in form. These tonguesare bent on bevel lines and are disposed at the back of the card and attheir beveled union with the body of the shield, engagement of theshield with the inclined edges 3 of the recesses 2 in the card, iseffected, so that accidental displacement of the shield in any directionwill be guarded against. By reason of the resilience of the tongues 7,they will form clamps to engage the card and prevent attachment of theshield to the card fro-m becoming loose.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is

l. The combination with an index card and a protecting shield covering alower portion of a face of the card, said shield provided at its endswith members to engage the other face of the card, said shield alsohavinga flange at its lower edge disposed under the lower edge of thecard.

2. The combination of an index card and a protecting shield covering alower portion of a face of the card, said shield provided at its endswith resilient members to engage the other face of the card, said shieldalso having a flange at its lower edge disposed under the lower edge ofthe card.

3. The combination of an index card having notches in its ends near vitslower edge, each of said notches having an inclined odge, and a shieldon the lower portion of a. face of the card and provided at its endswith resilient tongues to engage the other face of the card, said shieldengaging the inclined walls of said notches at the juncture of saidtongues with the body of the shield.

4. A shield for an index card, provided at its respective ends withresilient tongues bent on beveled lines and disposed approximatelyparallel with the body portion of the shield, said shield having aflange at its lower edge which projects at approximately right anglesfrom said lower edge.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
